Action always fails on folders whose name ends on .h or any other C-like suffix

Title says it all. Don't ask why we have folders named like that, and no, we physically cannot change the names =)

Just speculating like that, I imagine that adding a test to the find invocation like -type f (limit search to type that are files) would do the trick.

It cannot be before the -prune -o, (the -o is "or"), but can be somewhere in there

I didn't evaluate if there are some undesirable side effects in the current situation though.
